Draw a line-angle structure for the compound CH 3 CH 2 CH(CH 3)CH 2 CH 2 CH 3. The C–P–C bond angles are consistent with the notion that phosphorus predominantly uses the 3p orbitals for forming bonds and that there is little sp hybridization of the phosphorus atom. Bond angle can be calculated from the number of lone pair and bond pair present in the molecule. a. Get your answers by asking now. For the methyl cation, CH3+, the geometry, H–C–H bond angle, and hybridization of the carbon atom is best described as: CH3+ = A. trigonal planar, 120°, sp2 B.trigonal planar, 109.5°, sp2 C. … What is the predicted shape, bond angle, and hybridization for +CH3? Answer: Be is in group 2 and forms two bonds, one to each CH3. First of all i’m confused on how this is even possible as 2 hydrogens do not complete carbons’s octet, instead leaving it with 6 outer electrons. A) the C-O-C bond in an ether B) the C-N-C bond in a secondary amine C) the C-N-C bond in a quaternary amine D) the C-O-C bond in an alcohol ... (CH3)3N D) CH3CH2OCH3 E) CH3NHCH2CH3.
